  • Patent number: 8119374
    Abstract: This invention relates to the nucleotide sequence of coryneform bacteria coding for proteins which are involved in L-serine metabolism with reduced and switched off L-serine dehydratase activity. The invention also relates to microorganisms used in methods for producing L-serine.
    Type: Grant
    Filed: June 10, 2008
    Date of Patent: February 21, 2012
    Assignee: Forschungszentrum Julich GmbH
    Inventors: Petra Peters-Wendisch, Roman Netzer, Lothar Eggeling, Hermann Sahm
  • Patent number: 7732176
    Abstract: The invention relates to nucleotide sequences of coryneform bacteria that encode proteins that are involved in the biosynthesis of L-serine and to a method for producing L-serine. According to the invention, at least 79 amino acids at the C terminus of the wild-type serA sequence are deleted, thereby producing a 3-phosphoglycerate dehydrogenase having a reduced feedback inhibition by L-serine vis-à-vis the wild-type sequence.
    Type: Grant
    Filed: July 8, 2003
    Date of Patent: June 8, 2010

  • Publication number: 20090181435
    Abstract: The folic acid concentration in amino acid producing organisms is reduced or completely removed in order to increase the production of L-serine. The enzymes and genes, which are involved in the biosynthesis of folic acid, can be completely excluded or at least reduced in activity. In a preferred embodiment, SEQ ID NOs: 1-7 are utilized.

  • Patent number: 7267967
    Abstract: A pyruvate carboxylase gene having SEQ ID NO:1 as well as an amino acid sequence having SEQ ID NO:2 expressed by the pyruvate carboxylate gene are disclosed. Also disclosed is a method for microbial production of amino acids of the aspartate and/or glutamate family in which the pyruvate carboxylase activity is increased by genetically changing the pyruvate carboxylase gene having SEQ ID NO:1 through expression of a microorganism which produces the corresponding amino acid having SEQ ID NO:2.
    Type: Grant
    Filed: September 30, 1998
    Date of Patent: September 11, 2007
    Assignee: Forschungszentrum Julich GmbH
    Inventors: Bernd Eikmanns, Petra Peters-Wendisch, Hermann Sahm
  • Publication number: 20070202571
    Abstract: A method is disclosed for microbially producing L-amino acids of aspartate and/or glutamate families which comprises the step of: culturing a strain of Escherichia coli that produces said L-amino acids in a medium suitable for the production of an L-amino acid, whereby said Escherichia coli strain is transformed with a gene construct comprising a polynucleotide encoding an enzyme with pyruvate carboxylase activity.
